The Washington Metropolitan Police Department launched an investigation this week into whether Gregory and NBC violated city laws when he displayed what appeared to be a gun magazine on last week's show. Today, the police issued a statement, saying NBC had been told before last Sunday's show that it was “not permissible” to show a high-capacity gun magazine on air.
